SPECIFICATION forming part of Letters Patent N 0. 710,140, datedSeptember 30, 1902.

Application filed October 20, 1900.

To all whom, it may concern:

Be it known that 1, JOHN J. CHATTAWAY, a citizen of the United 'States,residing at Brooklyn, Kings county, State of New York, haveinventedanewand useful Improvement in Numbering-Machines, of which the following isa specification.

My invention relates to numbering-machines, and more particularly tothat class of numbering-machines designed to be adjusted so as to printnumbers consecutively or to number indefinitely at the will of theoperator.

The object of the invention is to provide a machine of this characterwhich shall be simple in construction and operation, strong, durable,and capable of being manufactured at a minimum cost, and particularly isit de-' signed to provide a machine in which the adjustments forconsecutive, duplicate, and repeat numbering may be easily andeffectively secured without soiling the fingers and without theintroduction of complex mechanism and in which the adjustment when oncesecured will be maintained and beclearly indicated by a device infullview at all times of the operator.

With these objects in view the invention consists in the combination ofelements and arrangement of parts defined in the claims.

The inventive idea involved is capable of a variety of mechanicalexpressions, .one of which I have shown in the accompanying drawings,which are to be regarded as illustrative only and not as defining thelimits of the invention.

In said drawings, Figure 1 is'a front elevation of a handnumbering-machine embodying my invention, and Fig. 2 is a rear elevationthereof. Fig. 3 is a top plan, and Fig; 4 a bottom plan, of a diskemployed to set the machine'in-the three positions for consecutive,duplicate, and repeat action. Fig. 5 is a side elevation of the machinewith a portion of the main frame removed. Fig. 6 is a cross-section onthe line 6 6, Fig. 5. Fig. 7 is a detail in end elevation, showing thecontrolling disk or dial in position for duplicate numbering; and Fig. 8is a like detail with the disk in position for consecutivenumber-' ing.Fig. 9 is a broken plan showing the -H toward the ratchet-wheels.

parts ,in position for duplicate numbering. Fig. 10 is a broken plan,partly inlsection, of

the parts in position for repeat numbering.

Fig. 11 is a top plan of the pawl-block and yoke withthe controlling andindexdisk or dial removed.

Referring to the drawings, A is the usual main frame, of inverted-Ushape, having a hollow stem B, supporting a yoke C, with a shaft 0, onwhich numbering-wheels E, each with a corresponding ratchet-wheel E, are

mounted to turn, said numbering and ratchet Wheels being yieldingly heldin position by any suitable detent, here shown as pawls L andcomb-spring K, though, if desired, ra-

dial detent-pins within the nu mbering-wheels E may be employed. Thestem B is normally held in its elevated position byaspring within thestem, reaching between the knob or upper end of the stem, and atransverse pin 0, ex-

tending through the boss A and slots B in the stem, so that the latteris free to reciprocate up and down past the pin 0. The yoke C is guidedin-the main frame A by projections thereon engaging vertical grooves inthe inner faces ofthe legs of the main frame. Such projections may beand preferably are the protruding endsof the shaft O, as shown; but theymay be independent projections on the yoke C, if desired. Pivoted on theshaft 0, inside of the yoke C, but embracing the numbering and ratchetwheels, is a yoke G, to which a pawl-block H is pivoted by rod R, acoiled spring S acting to press the pawl-block Hung to turn on'the shaft0 and on opposite sides of the numbering-wheels E are the ratchet-wheels-F F, (see Figs. 7, 8,9, and 10,) the wheel F haying nine shallowratchet notches or teeth f and one deep notch f, while the ratchetwheelF has five shallow notches f and five deep notches f alternating betweenthe shallow ones. The pawl-block H haspawls h,

-which engage the ratchet-wheels E.to actu-" ate the numbering-wheels E,and a pawl H which engages and turns the ratchet'wheel F, while a pawlM, freely pivoted on the rod R, engages and turns the idlerratchet-wheel F, said pawl being here shown as a gravity-pawl, though itis evident that a spring-pressed pawl would be the equivalent thereof.The

office of the ratchet-wheel F and pawl H is to control the engagement ofthe pawls h with the ratchet-wheels E of the numbering-wheels E in a waycommon and well understood in the art, and both ratchet-wheels F and Fare engaged bydetents, as pawls L, to retain them in proper position. I

Pivoted to the side of the main frame at U is a link G, Fig. 5, havingan upper slotted end engaging a pin projecting from the yoke G, whichpin is here shown as the projecting end of the rod R, and when the yokeG and pawl-yoke G are pressed downward in the operation ofthe machinepin R first moves down, carryingthepawl-block H till said pin reachesthe bottom of the slot in link G,when the furthcr down ward movement ofthe pawl-yoke G is arrested and the link swings inward, carrying thepawl-yoke and its supported pawls h and II inward with it around theperiphery of the. descending numbering and ratchet wheels, therebyadvancing the pawls to engage the'next tooth on the proper ratchetwheeland turn the corresponding num beringwheel one step as the yoke C isagain elevated by the spring in the stem B. p

The inking-pad normally rests in contact with the lower line of type onthe numberingwheels and preferably is removably secured to a plate P,Figs. 1 and 5, which plate has side armspp, pivoted at U U to the mainframe, links P P being pivotally connected to said arms 19 1) betweenthepivots U U and the plate P, while the other ends of the links P. P arepivoted on the shaft C. By this construction the inking-padis removedfrom the numbering-wheels on their downward movement and returnedthereto on their upward movement.

In the operation as thus far described the machine is only capable ofprinting numbers consecutively, the pawl H Fig. 8, which, it will beremembered, is rigid with the pawlplate H and pawls h, acting inconjunction with the ratchet-wheel F to control'the pawls h in theoperation of the numbering-wheels in the way well known in the art forprinting consecutive numbers. For the purpose of controlling the actionof the machine so as to enable it to print duplicate numbers or repeatany desired number indefinitely means are provided for lifting the pawlsit out of engagement with their ratchet-wheels and the pawl H out ofengagement with ratchet-wheel F at every other impression, so that thenumbering-wheels will only be advanced onestep for every twoimpressions, and hence will duplicate each number, or said means may beemployed to hold the pawls h and H continuously out of engagement withtheir respective ratchet-wheels, so that the n um beringwheels will notbe advanced at all, and hence the,

same number will be repeated over and over. Such means consist of a diskor dial-plate D. (Shown in site in Fig. 1, in top plan in Fig. 3, andbottom plan in Fig. 41.) This dial-plate or disk is pivotally mounted onthe pawl-plate H, Fig. 11, the general diameter of the disk being suchthat the pawl M is free to play past the periphery of the disk withoutengaging it, and this it does in the consecutive-printing action of themachine, neither the disk D nor the pawl M having any effect upon theaction of the machine during such time. The disk D is provided with aprojection d, extending beyond the periphery of the disk far enough sothat when the disk is turned, with the projection pointing horizontallyto the right, it will rest across pawl M and onthe pawl-yoke G, and thisengagement of the projection d with the yoke Gacts to lift the pawlplateH, to which disk D is attached, sufficiently to entirely preventengagement of the pawls h and H with their respective ratchet wheels,and hence the numbering-wheels will not be moved, and the same numberwill be repeated over and over. A second projection d is formed atanother part of the periphery of the disk D, said projection being longenough to extend over the pawl M, but not onto the yoke G. As hereshown, this projection is in the form of an eccentric withgradually-increasing radius; but such-eonstruction is not essential.tion (1 is positioned over the idler-pawl M, said pawl acts to lift thedisk D (and with it the pawl-plate H and pawls h and H when said pawl Mrests on a shallow notch f of the idler ratchet-wheel F; but whenidler-pawl M rests in a deep notch f of said ratchetwheel the pawl-plateis not lifted andlpawls h and H actuate their respective wheels, and asthe shallow notches f and deep notches f alternate it follows that thenumbering-wheels are moved only every other impression, and hence eachnumber is printed in duplicate.

The-disk D has the words Consecutive, Duplicate, and Repeat so arrangedon its face that when the disk is in position for the machine to printany one of these ways the word indicating such action will readhorizontally across the disk D. For the purpose of holdingthe disk inany adjusted position a spring-detent (here shown as a springpressed pinI,.Fig. 10) on the disk engaging notches J, Fig. 1-1, in the pawl-plateH may be used. Since the disk or dial D does not aifect the operation ofthe machine except when the projections 01 or d rest in either theposition shown in Fig. 9 for duplicate work or in the position shown inFig. 10 for repeat work, it is apparent that the disk form is notessential and that this element might be shaped like the thickenedsegmental part D, Fig. 4., the remaining portion of the disk D beingomitted, the essential feature being that there shall be an elementpivoted to the pawl-plate and having two arms or projectionscorresponding to the projections d d, which are capable of beingadjusted, the one so as to engage the pawl-yoke or other part and liftthe pawl-plate, and thus throw all the pawls h and H out of operation,and the other so as to lie in the path of the idler-pawl M when itengages the shallow notches f of idler ratchet-wheel F, and thus liftthe pawlplate and its pawls out of operation only on every other stroke.These conditions would be fulfilled by a bell-crank lever pivoted at itsangle to the pawl-plate and having one arm slightly longer than theother or by a threearmed or T-shaped piece pivoted to the pawlplate atthe angle and having one arm long enough to just miss the pawl M, asecond arm long enough to just cover the pawl, and a third and longerarm reaching beyond the pawl M and engaging the pawl-yoke or other partof the machine. It is also apparent that instead of the two projectionscl cl only one projection, as (I, might be employed, which projectionin' one position, as Fig. 9, would coact with idler-pawl M for duplicatenumbering and in another position engage the yoke or other part of themachine to withdraw the pawl plate H and its sustained pawls h and H outof operative engagement with their respective ratchet-wheels for repeatnumbering. These and other mechanical expressions of the inventive-ideaare're garded as the equivalents of the construction shown'for thepurposes of this invention and are intended to be included within thescope of the claims.

What is claimed is l. In a numbering-machine, the combination of thenumbering wheels and their ratchet-wheels,with a pawl-yoke, a pawl plateor block pivoted in said yoke, pawls secured to said plate andoperatively engaging said ratchet-wheels when in normal position, and apart pivoted to the pawl plate or block and adjustable into position toengage a part of the framework of the machine and withdraw said pawlsout of operative relation with said ratchet-wheels.

2. In a numbering-machine, the combination of the numbering-Wheels,ratchet-wheels controlling the movements of said numberingwheels, apivoted pawl plate or block, and pawls secured to said plate or blockand'engaging said ratchet-wheels for consecutive numbering, with a partpivoted to said'pawl plate or block and adjustable into relation with apart of the framework of the machine to turn said pawl plate or block inits pivot and thus withdraw said pawls from operative adjustable intoengagement with a part of the machine to withdraw the pawl plate orblock and its sustained pawls out of engagement with the ratchet-wheelsfor repeat num bering, and also adjustable over the. idlerpaw1,wherebyitwill be engaged by said idlerpawl when in the shallow notches of theidler ratchet-wheel, for duplicate numbering.

4. In a numbering-machine, the combina tion ofnumbering-wheels,ratchet-wheels controlling the movements of saidnumberingwheels, a pawl-yoke, a pawl plate or block pivoted to saidyoke,and pawls secured thereto, with a disk pivoted to said pawl-plateand having a part adjustable into engagement with said yoke to raise thepawl plate or block and its sustained pawls out of opera ti ve relationwith their ratchet-wheels, for repeat numbering.

5. In a numbering-machine, the combination ofnumbering-wheels,ratchet-wheels oon-' trolling the movements of saidnumbering- Wheels, a pawl-yoke, a pawl plate or block pivoted to saidyoke, pawls secured thereto, an idler ratchet-wheel having alternatedeep and shallow notches, and an idler-pawl engaging said notches,withamember pivoted to said pawl plate or block and having one partadjustable into the path of the idler-pawl when in the shallow notchesof the idler ratchetwheel,'for duplicate numbering, and another partadjustable into engagement with said pawl-yoke whereby said pawl plateor block and its sustained pawls are withdrawn from their ratchet-wheelsfor repeat numbering.
